FILTERING CUT-OFF RAIN-WATER SPOUT FOR CISTERNS.

SPECIFICATION forming part of Letters Patent No. 326,945, dated September 29, 1885.

Application filed April 1, 1885. (No model.)

To all whom it may concern.-

Be it known that I, JONATHAN E. BURDGE, a citizen of the United States, residing at Home City, in the county of Hamilton and State of Ohio, have invented a new and useful Filtering or Straining Cut-OffFeed Rain- WVater Spout for Cisterns, of which the following is a specification.

My invention relates to a cutoff and filtering spout for switching or turning into a cistern the rain-water running from the roof dischargepipe of a building.

My invention consists in providing at the discharge end of a rain waterconducting pipe an oscillating cylinder or tube, open throughout its length and having an opening cut in its circumference, intermediate its ends, which is filled with a straining wire-gauze, through which gauze-covered opening the dis charge-water flowing from the roofis emptied into the cistern in a filtered condition, and may be cut offfrom the cistern by turning the cylinder 21 part of a revolution, so as to bring said gauzeeovered opening out of line with the cisterneonnecting pipe, all of which will be fully hereinafter described.

In the accompanying drawings, Figure 1 is a longitudinal sectional elevation of my improved filtering cut-off cylinder, showing it concentrically mounted within an inwardlyfianged sleeve. Fig. 2 is a sectional elevation ofmyimprovement,showing the straining cut ofi' cylinder mounted within said flanged sleeve, as in Fig. 1, being turned so as to permit the water to flow into the cistern, the discharge end of the conducting-pipe, the cistern-spout, and the discharge or waste spoutbeing shown therein. Fig. 3 is a broken transverse sectional elevation of the eisternspout and the filtering cut-off cylinder.

0 represents an elbow, composing the lower discharge end of a down-spout for rain-water, leading from the root of a building to the ground.

2' represents a tube or cylinder fitting upon the mouth of down-spout 0, but preferably with an intervening rigid sleeve or thimble, P. In Figs. 1 and 2 one end of the sleeve 1 is shown encompassing the mouth of spout O, With its other end fitting within cylinder 2'.

Cylinder i is provided with an opening, F, in its circumference, which is covered with wiregauze B.

E represents a sleeve encircling the cylinder i. e e are inwardly-projecting flanges at both ends of sleeve E, the flange e encircling the thimble P and the flange e encircling the cylinder I D represents a waste pipe or spout, fitting upon the mouth of cylinder i.

T represents spider-arms in the discharge opening or mouth of cylinder 2.

'r is a central hub, which unites said arms T, and has a rod, It, projecting from it into and through the spout D.

\V is a manipulating-handle attached to the outer end of rod R.

H represents a spout fitting an opening, h, cut in the bottom of sleeve E, and suitably connected with a cistern.

In the operation of my device, the water passing through the down-spout O flows into the cistern through the gauzecovered opening B F, when said opening is brought opposite the opening it in the bottom of sleeve E, as shown in Figs. 2 and 3. The presence of the fine wire-gauze in the opening F prevents insects, chips, worms, leaves, or any similar foreign matter entering with the rain-water into the cistern, and it therefore serves as a strainer or filter to cleanse and purify the water.

Instead ofthe said gauze-covered opening, it is obvious that the cylinder icould be provided at the same place with small holes or perforations, through which the water could pass and be strained, but not as well as by means of the gauze, because the small holes made in the metal would. be more likely to become choked or closed up with the said foreign matter.

I prefer to arrange the cut-off filtering-cylinder at an inclination, as shown in the drawings, so that all foreign matter can more readily pass over the gauze-covered opening through the open waste-spout D, and also that the water cannot flow backwardly through the spout. The cylinder i is freely turned in its bearings formed by the thimble P and flange e by moving the handle Win either direction to bring opening F opposite the opening h into the cistern, or to arrange said opening out of linewith said cistern-opening, to permit the water to flow into the cistern on the one hand or tocause it to be cut off therefrom and dis charged from Waste-spout D on the other.

I clairn 1. The cornbi nation,with a rain-water downspout, O, of a cut-off tube, Z, which is open throughout its length and provided with a gauze-covered opening, B F, intermediate its ends, whereby the water is turned into or from a cistern and the debris or filtered deposit autoinatically carried out of the wasteoutl'et without obstruction, thereby maintaining a clear passageway for the discharge of the JONATHAN E. BURDGE.
